To allwhom it ma concern:

Be it known t at I, HEINRICH GosLAR, veterinary surgeon, a subject of the King of Prussia, residing at No. 22 Theresienstrasse, Aachen, in the Kingdom of Prussia, Empire of Germany, have invented certain new and useful Improvements in Processes of Conserving Organic Substances; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as. will enable others skilled in the art to which it. appertains to make and use the same.

The organic substances to be treatedby the present process are flesh, blood, animal glands and the juices thereof, and the juices of fruits and vegetables' p The organic substances contain, beside the components which are especially considered as'nutritive stufls such as albumen, fat and hydrates of carbon, other exceedingly valuable stuffs such as nutritive. salts, ferments, enzyms, hormons and the like. These latter stufls are of great importance for'the procsses of life in the animal body; on the one hand they directly influence the proper decomposition and utilization of the nutritious stufl's (albumen, fat and hydrates of carbon) themselves, on the other hand they have a beneficial influence on the operation of the several organs of the body. The value of these stuffs is the higher the less their original composition is changed by any circumstances. Such circumstances are especially chemical and thermal cooperations' with temperatures higher than that of the body or the blood, respectively, such as. form the basis in, most of the well-known processes for the conservationof organic substances. Through these chemical and thermal cooperations the original composition of the said components, which are contained in the organic substances of vegetable and animal kind and which, in dietetic and therapeutic respect, are essentially valuable for the processes of life in the body, is very much changed and their value inju'riously in- The object of my present invention is a prgficess for transferring into a durable form th e dietetically and therapeutically opera animal ind in which they are contained,

and keeping at the same time these stuffs as near their original composition as possible.

The process consists in adding to the organic substances to be conserved fibrinand gluten-containing stuffs ina finely crushed condition and drying the mixture at the lowest possible temperature; the process" is based on the. fact that a mixture of fibrincontaining and gluten-containing stufls obtains, when dried even at low temperatures,

a horny and exceedingly durable condition. As the drying takes place at low temperatures, 'no change occurs in the organic stulfs to be conserve i The fibrin may be employed in the form of finely crushed fibrin-containing animal Webs, preferably such as fibrin-containing parts of the blood and fibrin-containing organs, and the gluten in the form of grain.

, If it is desired for example to conserve the dietetically and therapeutically effective stufls such as nutritive salts, ferments, enzyms, hormons and the like, the process will be carried out as follows. The organic subin order to' obtain the juice in which the stufls to be conserved are chiefly contained.

If the substancescontained only little water, they are crushed in water and then pressed out, or an aqueous extract is made from them. The juice thus obtained is added to a mixture of gluten-forming grainflour and of fibrin-containing webs, such as coagulum of blood or fibrin-containing organs. After the whole mixture has been thoroughly mixed, it is subjected to an intensive grinding or kneading and pressing. v

The mass thus prepared is, in accordance with) its contents of water, worked into an unguentary paste which in turn is expanded in thin sheets, or by means of suitable mechanical devices formed into small plates or grooved longitudinal nodules Whichioifer a large surface. The thinly extended unguentary paste or the small plates and nodules are then subjectedto an air-current of suitable strengthand of .a temperature of not more than 104 Fahrenheit. Under the influence of this air-current the mixture formed in the manner "described turns into a horny,

exceedingly durable condition. In /this hardened condition, the dried product al:

vlows of a very far-going mechanical; disruption b'y means of suitable, milling devices in such a manner that the several parts of the product are rolled and ground as finely as possible, this being of special importance for the digestion of the starch-flourand cellulose-containing ingredients of the product.

By successively impregnating the product several times and thereafter drying and grinding the same, such a fine mechanical disrlrption of the starch-flour and cellulosecontaining ingredients is obtained as cannot be effected by the well-known ordinary grinding of the ingredients of the grain.

The perfect disruption of the ingredients 4 and if these substances themselves contain enoughfibrin (muscle flesh, animal organs,

4 blood and the like), glutten-forming'grainflour is directly added-to the same; the mixture is thereupon further prepared in'the manner already indicated. If, however, the stuffs to be conserved, such as vegetable stuffs for example, do not contain any or only little fibrin, these stuffs are added to a mixture of finely divided fibrin-containing animal substances and gluten-forming grain-flour. "In case moisture should be wanted during the'action of mixing, distilled water may be added. For cleaning the surfaces of the organic substances to be prepared hydrogen peroxid may be used.

Stuffs -which are easily .decomposable are .kept cool in asuitable manner until their preparation, inorder to prevent the developmentof schizomysetes. It is therefore apparent that by the present process a product can be obtained which is highly durableand easily digestible at the same time.

The above-described transference of organimsubstances into a durable condition,

WlllCh is relatively simple to effect and -which takes place so as to maintain the nativity of their components without the use of temperatures higher than the tem-- perature of the body and withoutthe ap-' plication of chemical additions,v is based on the fact that, when thoroughly mixing the glutenand fibrin-containing moist stuflTs grain-flour, v ther continuous grinding kneading and and thereupon grinding, kneading and pressing the same, the gluten which in its original form was already contained in .the

is produced. During the furpressing the starch-flourand cellulose-containing stuffs are, as so-called bearers of the substances to be conserved, impregnated with the gluten as well as with the fibrin.

In consequence of the rapid extraction of water effected by means of a heated a rcurrent of low temperature the mixture of the gluten and fibrin and together with this mixture the organic stufis impregnated with the same are brought into a very hard, horny condition. A low temperature (temperature of the body) is sufficient in order to produce this horny condition, as on account of the rapid extraction of the water the gluten and the fibrin while otherwise easily decomposable, turn into a durable form already at low temperatures. The extraction of moisture prevents a progressive development of any schizomysetes which might be contained in the mass. The schizomysetes are kept in place in the mass, when this during the drying becomes horny, and their growth will be checked from lack of moistureor they even perish.

Having thus described my invention, what I claim is:

1. A process for conserving flesh, blood,

the juices of fruit and vegetable and simultaneously maintaining the nativity of their ingredients, which consists in thoroughly mixing finely divided fibrin-containing webs and gluten-containing grain-flour, adding to this mixture the organic substances, and

then forming the whole mass'thus prepared animal glands and the juices thereof, and v finely divided fibrin and gluten-containing substances with the organic substances to be conserved, in the presence of moisture rolling the mass into thin sheets, and quickly drying the sheets at a low temperature.

In testimony whereof I have signed my name to this specification in the presence of g two subscribing witnesses.
